| Barnes' Notes on the Bible For every one that useth milk - Referring to the food of children. The apostle has in view here those Christians who resemble children in this respect, that they are not capable of receiving the stronger food adapted to those of mature age. Is unskilful - Inexperienced; who has not skill to perform anything. The word is properly applied to one who has not experience or skill, or who is ignorant. Here it does not mean that they were not true Christians - but that they had not the experience or skill requisite to enable them to understand the higher mysteries of the Christian religion. In the word of righteousness - The doctrine respecting the way in which men become righteous, or the way of salvation by the Redeemer; see the notes on Romans 1:17. For He is a babe - That is, in religious matters. He understands the great system only as a child may. It is common to speak of "babes in knowledge," as denoting a state of ignorance.
Clarke's Commentary on the BibleFor every one that useth milk - It is very likely that the apostle, by using this term, refers to the doctrines of the law, which were only the rudiments of religion, and were intended to lead us to Christ, that we might be justified by faith. The word of righteousness - Αογος δικαιοσυνης· The doctrine of justification. I believe this to be the apostle's meaning. He that uses milk - rests in the ceremonies and observances of the law, is unskilful in the doctrine of justification; for this requires faith in the sacrificial death of the promised Messiah.
Gill's Exposition of the Entire BibleFor everyone that useth milk,.... And sits down contented with the first principles of the Gospel, such as are easily taken in and digested; or makes use of the ceremonial law, as a schoolmaster to teach him the Gospel: is unskilful in the word of righteousness; the Gospel, which is a doctrine of righteousness; not of works of righteousness done by men, and of justification by them, or of a man's own righteousness; but of the pure, perfect, and everlasting righteousness of Christ: and it is called so, because it is the means of stripping a man of his own righteousness; and of revealing the righteousness of Christ unto him; and of working faith in him to lay hold upon it; and of discovering the agreement there is between the righteousness of Christ, and the justice of God; and of teaching men to live soberly, righteously, and godly: and such are unskilful in it, who either have no knowledge of the doctrine of justification; of the matter of it, Christ's righteousness; of the form of it, by imputation; and of the date of it, before faith: or have a very confused notion of it, joining their own works with Christ's righteousness, for justification, as many judaizing professors did; or who, if they have a notional knowledge of it, have no practical concern in it; do not believe with the heart unto righteousness; have not the experience, sweetness, and power of this doctrine upon them; and do not live lives agreeable to it: for he is a babe. This word is used sometimes by way of commendation, and is expressive of some good characters of the saints; such as harmlessness and inoffensiveness, humility, and meekness, a desire after the sincere milk of the word, freedom from rancour and malice, hypocrisy and guile; but here it is used by way of reproach, and denotes levity and inconstancy, ignorance and non-proficiency, want of digestion of strong meat, and incapacity to take care of themselves, as standing in need of tutors and governors.
Vincent's Word StudiesUseth (μετέχων) Rend. partakes of. See on Hebrews 1:9; see on Hebrews 2:14; see on Hebrews 3:1, Hebrews 3:14. Unskilful (ἄπειρος) N.T.o. Rend. unskilled or inexperienced. In the word of righteousness (λόγου δικαιοσύνης) The phrase N.T.o. The genitive δικαιοσύνης of righteousness is combined in N.T. with way, God, gift, instruments, servants, law, ministration, fruit and fruits, ministers, hope, breastplate, crown, king, preacher. It is a mistake to attempt to give the phrase here a concrete meaning. It signifies simply a word of normally right character. It is not equals the Christian revelation, which would require the article. Probably, however, in the foreground of the writer's thought was the word spoken by the Son (Hebrews 1:2); the salvation which at first was spoken by the Lord (Hebrews 2:3). A babe (νήπιος) See on Romans 2:20; see on 1 Corinthians 3:1; see on Ephesians 4:14.
Geneva Study BibleFor every one that useth milk is unskilful in the {l} word of righteousness: for he is a babe. (l) In the word that teaches righteousness.
People's New Testament 5:13 For every one that useth milk... is a babe. Those who only understand the A B C's of Christianity are only babes in Christ, like the babes whose food is milk. Is unskilful in the word of righteousness. Such an one cannot handle the word of righteousness skillfully.
Wesley's Notes 5:13 Every one that useth milk - That neither desires, nor can digest, anything else: otherwise strong men use milk; but not milk chiefly, and much less that only. Is unexperienced in the word of righteousness - The sublimer truths of the gospel. Such are all who desire and can digest nothing but the doctrine of justification and imputed righteousness.
King James Translators' Notesis unskillful: Gr. hath no experience
Jamieson-Fausset-Brown Bible Commentary13. useth-Greek, "partaketh," that is, taketh as his portion. Even strong men partake of milk, but do not make milk their chief, much less their sole, diet. the word of righteousness-the Gospel wherein "the righteousness of God is revealed from faith to faith" (Ro 1:17), and which is called "the ministration of righteousness" (2Co 3:9). This includes the doctrine of justification and sanctification: the first principles, as well as the perfection, of the doctrine of Christ: the nature of the offices and person of Christ as the true Melchisedec, that is, "King of righteousness" (compare Mt 3:15).
Matthew Henry's Concise Commentary5:11-14 Dull hearers make the preaching of the gospel difficult, and even those who have some faith may be dull hearers, and slow to believe. Much is looked for from those to whom much is given. To be unskilful, denotes want of experience in the things of the gospel. Christian experience is a spiritual sense, taste, or relish of the goodness, sweetness, and excellence of the truths of the gospel. And no tongue can express the satisfaction which the soul receives, from a sense of Divine goodness, grace, and love to it in Christ.
Matthew Henry's Whole Bible CommentaryVerses 10-14 Here the apostle returns to what he had in v. 6 cited out of Ps. 110, concerning the peculiar order of the priesthood of Christ, that is, the order of Melchisedec. And here, I. He declares he had many things which he could say to them concerning this mysterious person called Melchisedec, whose priesthood was eternal, and therefore the salvation procured thereby should be eternal also. We have a more particular account of this Melchisedec in ch. 7. Some think the things which the apostle means, that were hard to be uttered, were not so much concerning Melchisedec himself as concerning Christ, of whom Melchisedec was the type. And doubtless this apostle had many things to say concerning Christ that were very mysterious, hard to be uttered; there are great mysteries in the person and offices of the Redeemer; Christianity is the great mystery of godliness. II. He assigns the reason why he did not say all those things concerning Christ, our Melchisedec, that he had to say, and what it was that made it so difficult for him to utter them, namely, the dulness of the Hebrews to whom he wrote: You are dull of hearing. There is a difficulty in the things themselves, and there may be a weakness in the ministers of the gospel to speak clearly about these things; but generally the fault is in the hearers. Dull hearers make the preaching of the gospel a difficult thing, and even many who have some faith are but dull hearers, dull of understanding and slow to believe; the understanding is weak, and does not apprehend these spiritual things; the memory is weak, and does not retain them. III. He insists upon the faultiness of this infirmity of theirs. It was not a mere natural infirmity, but it was a sinful infirmity, and more in them than others, by reason of the singular advantages they had enjoyed for improving in the knowledge of Christ: For when, for the time, you ought to be teachers, you have need that one teach you again which are the first principles of the oracles of God, v. 12. Here observe, 1. What proficiency might have been reasonably expected from these Hebrews-that they might have been so well instructed in the doctrine of the gospel as to have been teachers of others. Hence learn, (1.) God takes notice of the time and helps we have for gaining scripture-knowledge. (2.) From those to whom much is given much is expected. (3.) Those who have a good understanding in the gospel should be teachers of other, if not in a public, yet in a private station. (4.) None should take upon them to be teachers of others, but those who have made a good improvement in spiritual knowledge themselves. 2. Observe the sad disappointment of those just expectations: You have need that one should teach you again, etc. Here note, (1.) In the oracles of God there are some first principles, plain to be understood and necessary to be learned. (2.) There are also deep and sublime mysteries, which those should search into who have learned the first principles, that so they may stand complete in the whole will of God. (3.) Some persons, instead of going forward in Christian knowledge, forget the very first principles that they had learned long ago; and indeed those that are not improving under the means of grace will be losing. (4.) It is a sin and shame for persons that are men for their age and standing in the church to be children and babes in understanding. IV. The apostle shows how the various doctrines of the gospel must be dispensed to different persons. There are in the church babes and persons of full age (v. 12-14), and there are in the gospel milk and strong meat. Observe, 1. Those that are babes, unskillful in the word of righteousness, must be fed with milk; they must be entertained with the plainest truths, and these delivered in the plainest manner; there must be line upon line, precept upon precept, here a little, and there a little, Isa. 28:10. Christ despises not his babes; he has provided suitable food for them. It is good to be babes in Christ, but not always to continue in that childish state; we should endeavor to pass the infant state; we should always remain in malice children, but in understanding we should grow up to a manly maturity. 2. There is strong meat for those that are of full age, v. 14. The deeper mysteries of religion belong to those that are of a higher class in the school of Christ, who have learned the first principles and well improved them; so that by reason of use they have their senses exercised to discern both good and evil, duty and sin, truth and error. Observe, (1.) There have been always in the Christian state children, young men, and fathers. (2.) Every true Christian, having received a principle of spiritual life from God, stands in need of nourishment to preserve that life. (3.) The word of God is food and nourishment to the life of grace: As new-born babes desire the sincere milk of the word that you may grow thereby. (4.) It is the wisdom of ministers rightly to divide the word of truth, and to give to every one his portion-milk to babes, and strong meat to those of full age. (5.) There are spiritual senses as well as those that are natural. There is a spiritual eye, a spiritual appetite, a spiritual taste; the soul has its sensations as well as the body; these are much depraved and lost by sin, but they are recovered by grace. (6.) It is by use and exercise that these senses are improved, made more quick and strong to taste the sweetness of what is good and true, and the bitterness of what is false and evil. Not only reason and faith, but spiritual sense, will teach men to distinguish between what is pleasing and what is provoking to God, between what is helpful and what is hurtful to our own souls. |
